Playing Space Invaders with Real Fire and Lasers Making a Space Invaders game is up there on the list of most unconventional things you could do with a laser cutter. In watching the tiny little ships burst into flames, [Martin Raynsford’s] modification has got to be one of the more dangerous looking ones we’ve seen as well. [Martin] always had the desire to make a tangible version of the classic game. Since his Whitetooth A1 laser cutter already contained the bulk of the moving hardware needed, not to mention an actual high powered laser to “pew pew” with, he decided it was the perfect starting point for such a project. The game is played looking down into the cutter since the laser of course fires in that direction, however a basic webcam is mounted to the laser assembly so that you can view the game on a computer screen at the proper perspective.
Bilderberg Group The Bilderberg Group, Bilderberg conference, Bilderberg meetings or Bilderberg Club is an annual private conference of approximately 120–150 political leaders and experts from industry, finance, academia and the media. About two thirds of the participants come from Europe and the rest from North America; one third from politics and government and the rest from other fields. §Origin The original conference was held at the Hotel de Bilderberg in Oosterbeek, Netherlands, from 29 to 31 May 1954. RSA Algorithm The RSA algorithm is named after Ron Rivest, Adi Shamir and Len Adleman, who invented it in 1977 [RIVE78]. The basic technique was first discovered in 1973 by Clifford Cocks [COCK73] of CESG (part of the British GCHQ) but this was a secret until 1997. The patent taken out by RSA Labs has expired. The RSA cryptosystem is the most widely-used public key cryptography algorithm in the world. It can be used to encrypt a message without the need to exchange a secret key separately. The RSA algorithm can be used for both public key encryption and digital signatures.
Hour of Code Minecraft Hour of Code Grades 2+ | Blocks Moana: Wayfinding with Code Make a Flappy game Cricket Hill Collection Hand-marbled paper, gouache, and ink on paper by Sophie B. During Field Work Term, I would absolutely love to work with the Pittsburgh Pirates, a Major League Baseball team. In 2011, I fell in love with baseball, specifically Pirates baseball, and haven’t stopped since. I watch, listen to, or follow every game, gathering information about every pitcher, batter, and umpire that I can.

AES encryption of files in Python with PyCrypto [Updated 15.11.2013: passing IV is required in the new PyCrypto] The PyCrypto module seems to provide all one needs for employing strong cryptography in a program. It wraps a highly optimized C implementation of many popular encryption algorithms with a Python interface. PyCrypto can be built from source on Linux, and Windows binaries for various versions of Python 2.x were kindly made available by Michael Foord on this page. My only gripe with PyCrypto is its documentation. The auto-generated API doc is next to useless, and this overview is somewhat dated and didn’t address the questions I had about the module. The Top 10 Existential Movies of All Time Browsing through my DVD collection recently I realized that I have a fairly decent selection of what can be called 'existential movies' -- philosophical films that study the nature of existence and what it means to be alive. It's debatable as to what defines the 'quintessential' existential movie, but ultimately it must speak to the human condition and reframe it in such a way that the viewer gains an enhanced appreciation of their own existence and situation in life. These are the kinds of films that you find yourself reflecting back upon time and time again as you engage in your own day-to-day life, struggles and relationships. Thus, I present to you the top 10 existential movies of all time: 10.
